'''AT&T Corporation''' originally the '''American Telephone and Telegraph Company''', is the subsidiary of AT&T that provides voice, video, data, and Internet telecommunications and professional services to businesses, consumers, and government agencies. Founded in 1885 as the original American Telephone and Telegraph Company, it was at times the world's largest telephone company, the world's largest cable television operator, and a regulated monopoly. At its peak in the 1950s and 1960s, it employed one million people and its revenue was roughly $3 billion annually. In 2005, AT&T was purchased by Baby Bell and former subsidiary SBC Communications for more than $16 billion ($ in present-day terms). SBC then changed its name to AT&T|AT&T Inc.
